Skip It, Below Average Sushi.
Yummy House was a dissapointment to me. Compared to all of the other Upper East Side sushi restaurants it trailed them in every category.
We ordered in from Yummy last night and were highly dissapointed with the sushi. The fish was fresh but it did not taste nearly as well as other sushi restaurants. The maki rolls were all coming apart when we got them, thats a big negative. I needed to rebuild my food before I could eat it. The rolls are small and frankly just average as I stated above. Their cooked food however is pretty good. We had the chicken negimaki and that was very good, their miso soup was good as well.
To sum it up, I would recommend Akita and Hoikkado over Yummy House. They both are far superior with their sushi and their presentation.
